Examples of org.apache.hadoop.metrics.util.MetricsLongValue

org.apache.hadoop.metrics.util.MetricsLongValue
The MetricsLongValue class is for a metric that is not time varied but changes only when it is set. Each time its value is set, it is published only *once* at the next update call.

      new RegionServerDynamicMetrics();
    return metrics;

  public synchronized void setNumericMetric(String name, long amt) {

    if (m == null) {
      m = new MetricsLongValue(name, this.registry);
      try {
        if (updateMbeanInfoIfMetricsListChanged != null) {
          updateMbeanInfoIfMetricsListChanged.invoke(this.rsDynamicStatistics,
              new Object[]{});
        }
      } catch (Exception e) {
        LOG.error(e);
      }
